          Abstract

          Abstract We provide a floristic inventory of Angiosperms from rocky outcrops of the Área de Proteção Ambiental Pedra do Elefante, Espírito Santo, Brazil. Fieldwork was performed monthly from March/2015 to July/2016. A checklist with 302 species belonging to 219 genera and 74 families is provided. Bromeliaceae, Orchidaceae, Fabaceae, Euphorbiaceae, Apocynaceae, Asteraceae, Cactaceae, Convolvulaceae, Rubiaceae, Bignoniaceae and Cyperaceae are the richest families with around 50% of the listed species. One hundred forty seven species are exclusively rupicolous, 125 spp. exclusively terricolous, 26 spp. are epiphytes, and six species are found as both rupicolous and terricolous. Phanerophytes and chamaephytes were predominant life forms. Our results added 18 new records to the Espírito Santo state, indicated the occurrence of nine endemic species for the state and noticed that only 55 taxa of the total of species have threat assessments according to IUCN.

          Resumo O objetivo deste trabalho foi realizar o inventário florístico das Angiospermas dos afloramentos rochosos da Área de Proteção Ambiental Pedra do Elefante, Espírito Santo, Brasil. Expedições de coleta foram realizadas mensalmente de março/2015 a julho/2016. Um total de 302 espécies pertencentes a 219 gêneros e 74 famílias foram encontradas. Bromeliaceae, Orchidaceae, Fabaceae, Euphorbiaceae, Apocynaceae, Asteraceae, Cactaceae, Convolvulaceae, Rubiaceae, Bignoniaceae e Cyperaceae são as famílias mais ricas com cerca de 50% de representatividade das espécies listadas. Os táxons exclusivamente rupícolas são representados por 147 espécies enquanto 125 spp. São exclusivamente terrícolas, 26 spp. são epífitas e seis espécies são encontradas como tanto como rupícolas quanto terrícolas. As formas de vida predominantes foram fanerófitas e as caméfitas. Nossos resultados adicionaram 18 novos registros ao estado do Espírito Santo, indicaram a ocorrência de nove espécies endêmicas para o estado e indicam que apenas 55 táxons do total de espécies encontradas possuem avaliações de quanto às categorias de ameaça de acordo com a UICN.

            Tropical inselbergs: habitat types, adaptive strategies and diversity patterns

            Inselbergs are isolated rock outcrops that rise abruptly above the surrounding plains. Granitic and gneissic inselbergs are geologically and geomorphologically old and occur throughout a broad spectrum of climatic zones. They form microclimatically and edaphically dry growth sites that support a highly specialized vegetation. Based on physiognomic criteria a number of habitat types can be distinguished that are widespread on inselbergs (e.g. ephemeral flush vegetation, monocotyledonous mats, rock pools). Three hot spots of global inselberg plant diversity can be identified which are both rich in species and endemics: a) southeastern Brazil, b) Madagascar and c) southwestern Australia.

              Angiosperm Checklist of Espírito Santo: using electronic tools to improve the knowledge of an Atlantic Forest biodiversity hotspot

              Abstract A checklist of angiosperm species for the state of Espírito Santo, Brazil is presented. A total of 6,204 native species was recorded, representing an increase of 16% in species richness for the area. Espírito Santo shelters 32% of the native species of Brazil's Atlantic Forest and holds 516 endemic species (8.3% of the total registered taxa for the State). Bromeliaceae and Orchidaceae are the families with highest number of endemic species (142 spp. and 80 spp., respectively), followed by Myrtaceae (33 spp.), Melastomataceae (30 spp.), and Araceae (23 spp.). This paper represents an important landmark for future research in plant diversity in Espírito Santo, and highlights the importance of consulting online databases in order to update the knowledge presented by the Brazilian flora checklist.
